[USER32] GetQueueStatus() should not return 0 when passing QS_ALLINPUT flag that includes QS_RAWINPUT (#4115)

GTK applications call GetQueueStatus(QS_ALLINPUT), where QS_ALLINPUT
specifies the QS_RAWINPUT flag as well, when these are compiled for
Windows XP+, and they expect the call to succeed on this platform.

On one side, ReactOS does not currently support this flag at all, but
since it claims to be XP/2003-compatible, applications may implicitly
expect the flag to be supported by GetQueueStatus() and the function
*NOT* failing when this flag is set.
(Later GTK apps don't care and just call GetQueueStatus(QS_ALLINPUT)
that includes QS_RAWINPUT, and therefore would fail as well on e.g.
Windows 2000...)

Otherwise, an observable effect is that some versions of libgdk-win32-2.0.0.dll
enter into an infinite loop when calling GetQueueStatus(QS_ALLINPUT),
since this call always failed on ReactOS.

On the other side, however, we should honour our winetests that handle
the presence of the QS_RAWINPUT flag and behave differently accordingly.
But since we do not support QS_RAWINPUT yet, we should keep their old
behaviour where QS_RAWINPUT is unused.

Thus, in order to accomodate both sides, we don't fail the GetQueueStatus()
call, but just set the ERROR_INVALID_FLAGS last error and continue it.

This fixes:
'All user32:TrackMouseEvent tests'
CORE-15686: Gimp 2.8.22 from rapps hangs after startup with 90%-100% CPU usage
and many dupes of that ticket like:
CORE-17551: Ardour hangs at the first start (GTK2 issue)
CORE-15151: newer "Inkscape 0.92.3" is unusable due to WIN32SS message queue lockup
CORE-14086: RawTherapee 5.0-r1-gtk2 fails to start (using 100% CPU)
CORE-11850: Geany 1.28 hangs with endless MsqSendMessage timed out
CORE-8475: Wireshark hangs after launch

It will also slightly appease, but not entirely fix:
CORE-8217: 3D Text ScreenSaver freezes system

What is ReactOS?

ReactOS™ is an Open Source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft® Windows™ NT family of operating systems (NT4, 2000, XP, 2003, Vista, Seven).

The ReactOS project, although currently focused on Windows Server 2003 compatibility, is always keeping an eye toward compatibility with Windows Vista and future Windows NT releases.

The code of ReactOS is licensed under GNU GPL 2.0.

ReactOS is currently an Alpha quality operating system. This means that ReactOS is under heavy development, things may not work well and it can corrupt the data present on your hard disk. It is recommended to test ReactOS on a virtual machine or on a computer with no sensitive or critical data!

Building

appveyor.badge travis.badge rosbewin.badge rosbeunix.badge coverity.badge

To build the system it is strongly advised to use the ReactOS Build Environment (RosBE). Up-to-date versions for Windows and for Unix/GNU-Linux are available from our download page at: "Build Environment".

Alternatively one can use Microsoft Visual C++ (MSVC) version 2010+. Building with MSVC is covered here: "Visual Studio or Microsoft Visual C++".

Binaries

To build ReactOS you must run the configure script in the directory you want to have your build files. Choose configure.cmd or configure.sh depending on your system. Then run ninja <modulename> to build a module you want or just ninja to build all modules.

Bootable images

To build a bootable CD image run ninja bootcd from the build directory. This will create a CD image with a filename bootcd.iso.

See "Building ReactOS" for more details.

You can always download fresh binary builds of bootable images from the "Daily builds" page.

Installing

By default, ReactOS currently can only be installed on a machine that has a FAT16 or FAT32 partition as the active (bootable) partition. The partition on which ReactOS is to be installed (which may or may not be the bootable partition) must also be formatted as FAT16 or FAT32. ReactOS Setup can format the partitions if needed.

Starting 0.4.10, ReactOS can be installed using the BtrFS file system. But consider this as an experimental feature and thus regressions not triggered on FAT setup may be observed.

To install ReactOS from the bootable CD distribution, extract the archive contents. Then burn the CD image, boot from it, and follow the instructions.

See "Installing ReactOS" Wiki page or INSTALL for more details.

Testing

If you discover a bug in ReactOS search on JIRA first - it might be reported already. If not report the bug providing logs and as much information as possible.

See "File Bugs" for a guide.

NOTE: The bug tracker is not for discussions. Please use #reactos Freenode IRC channel or our forum.

Contributing prwelcome.badge

We are always looking for developers! Check how to contribute if you are willing to participate.

You can also support ReactOS by donating! We rely on our backers to maintain our servers and accelerate development by hiring full-time devs.

More information

ReactOS is a Free and Open Source operating system based on the Windows architecture, providing support for existing applications and drivers, and an alternative to the current dominant consumer operating system.

It is not another wrapper built on Linux, like WINE. It does not attempt or plan to compete with WINE; in fact, the user-mode part of ReactOS is almost entirely WINE-based and our two teams have cooperated closely in the past.

ReactOS is also not "yet another OS". It does not attempt to be a third player like any other alternative OS out there. People are not meant to uninstall Linux and use ReactOS instead; ReactOS is a replacement for Windows users who want a Windows replacement that behaves just like Windows.

More information is available at: reactos.org.

Also see the media/doc subdirectory for some sparse notes.

Who is responsible

Active devs are listed as members of GitHub organization. See also the CREDITS file for others.

Code mirrors

The main development is done on GitHub. We have an alternative mirror in case GitHub is down.

There is also an obsolete SVN archive repository that is kept for historical purposes.
